Hamilton Cams 178/208 Street Cam 89-18 5.9L / 6.7L CumminsThis cam will help to drastically reduce exhaust gas recirculation (EGR) and provide more fresh, cool air for your engine. That means less particulate matter, lower exhaust gas temperatures (EGT's), and better fuel economy! Originally, Hamilton built this cam for 6. 7L Cummins owners looking to create overall efficiency while keeping all of the factory emissions system intact.

This cam will help to drastically reduce exhaust gas recirculation (EGR) and provide more fresh, cool air for your engine. That means less particulate matter, lower exhaust gas temperatures (EGT's), and better fuel economy!

Originally, Hamilton built this cam for 6.7L Cummins owners looking to create overall efficiency while keeping all of the factory emissions system intact. If you have accepted that DPFs are here to stay, but you want to make more power and you don't like wasting fuel to clean out your DPF, this is your cam! And for owners of 5.9L's, after further development, Hamilton learned that this cam also worked extremely well in these models for creating efficiency in moderate street trucks. Due to its short duration and wide lobe separation angle, it also has the least overlap (when intake and exhaust valves are open at the same time) of any of Hamilton's cams, which helps to eliminate in cylinder EGR on engines that have higher drive pressure than boost. This occurrence is usually found on trucks with stock turbos with a restrictive turbine housing.

CAST IRON VS STEEL CAMSHAFT COMPARISON:

When it comes to valvetrain performance and long-term reliability, steel camshafts offer clear advantages over traditional cast iron designs. Steel is significantly stronger and more resistant to cracking, flexing, and wear under high-load conditions, making it ideal for engines running heavier valve springs, higher RPM, increased boost, or elevated cylinder pressures. Unlike cast iron, which can be brittle and more prone to lobe wear or failure in demanding applications, steel maintains its structural integrity and precise lobe shape over time. This added rigidity helps maintain accurate valve timing under stress, improving consistency, efficiency, and overall durability. Whether you’re towing heavy, racing, or building a high-performance daily driver, a steel camshaft provides the strength and longevity needed to protect your investment and keep your engine performing at its best.

If you live at high altitudes, tow heavy, or are looking for the best efficiency possible for highway driving, this cam will be your best friend. And for those running larger turbos on a common rail engine, this cam will aid in low RPM spool up, as well.

Love the way these turned out in my office! I connected 3 shelves in a row across the wall to make one long shelf and it looks great!

Nice looking. Not very sturdy. Easy to install.
Size: 40x7 2Pcs, Color: White, Size: 40x7 2Pcs, Color: White
Update: The shelf slopes at about a 45° angle when you put anything more than about a pound on the outside edge of it. Perfectly fine up against the wall. Just seems like the braces inside aren't long enough to really give the stability needed. Bracket is nice and tight against the wall. Had to add braces underneath to hold a small plant, a photo and a small container. Wa sloping more and more each week The shelves look great and we're pretty easy to install. They have a single bracket that is very easy to mount to the wall and get nice and level.. The downside is that the bracket isn't long enough to go between studs. This seems like a pretty simple oversight. I mean why wouldn't you make it long enough to go stud to stud? Secondly and maybe more fatally the bars that go inside the shelf to support them coming out from the wall are significantly shorter than the depth of the shelf. Unfortunately this means the shelf is only supported the first few inches coming out from the wall so there is the potential for a slight lean forward.. The anchors they send are trash. Cheap soft plastic that just tears and bends with a screwdriver. I would suggest spending $2 and grabbing your own anchors from Ace or home Depot. The shelves are essentially made of a high grade cardboard kind of wood. They are not going to support much weight or last for years and years however there incredibly affordable and look nice and easy to install. Long as your expectations are right you'll be happy.

Great shelves!
Color: Grey, Size: 55 Inch, Style: 2 Pack
This shelf is lovely--simple and modern. My handyman said it was easy to install AND made a note to buy it for his own rental units because he said the internal supports were very sturdy. Fast delivery and exactly as described--and the price is nice, too.
